Composition and diversity of arbuscular mycorrhizal fungi spore associated with different land-use types in tropical gold mine

Abstract

Understanding the composition and diversity of arbuscular mycorrhizal fungi (AMF) is imperative for potentially enhancing their ecological role in different terrestrial ecosystems. Land use can have substantial effects on AMF species composition and diversity, but such effects have been explored less in tropical landscapes. In this study, we assessed the effects of disturbances on AMF species richness, observed the potential development of AMF types to produce mycorrhizal biofertilizer bioinoculants. This study was conducted identifying and selecting AMFs was for the purpose of managing post-mining land in Bombana District, Southeast Sulawesi, Indonesia. AMF spores collected from the field and trap culture were directly isolated and morphologically identified. A total of 15 AMF species were identified, including 11 species from field samples and 9 species from trap cultures. We noted that five AMF species were unique to field conditions and 5 AMF species were uniquely isolated from trap culture. It appears that Glomeraceae family contributed the highest number of species in all land-use types. Glomus sp. 1 was the most frequent species found in all land-use types. The Simpson's index, Shannon index and evenness ranged from 1.60 ± 0.51 to 2.40 ± 0.40; 0.41 ± 0.17 to 0.62 ± 0.17; 0.25 ± 0.10 to 0.39 ± 0.11, respectively. In this study, we found three new records of AMF species including Entrophospora colombiana, Sclerocystis microcarpa and Glomus coronatum for Indonesia, i.e. from this study, it is clear that different land-use types affected AMF spore composition and species diversity. All AMF species found in this study were then applied to the land to improve land quality.

Richness of Arbuscular Mycorrhizal Fungi Under Different Agroforestry Practices in the Drylands of Southern Ethiopia

“…The AMF spore abundance recorded in this study were comparable with the findings from different tropical areas [32,39,41,44,85]. Spore densities in this study were higher than the findings conducted by [36,89,90]and lower than those obtained by [91] in Ivory Coast. The differences might be the identification techniques and soil disturbance [8].…”

Soil properties change, and arbuscular mycorrhizal fungi associated with plants growing on the post-gold mining land of Bombana, Indonesia

“…Results of this study showed that the dominant AMF family was Glomeraceae at a percentage of 70%. Several studies also showed the same results, in which Glomeraceae was dominant in the post-mining area of nickel (Prayudyaningsih et al, 2019), coal (Ezeokoli et al, 2020), asphalt (Tuheteru et al, 2022), gold (Tuheteru et al, 2020), and limestone (Suting and Devi, 2021). Glomeracecae was reported to be dominant in the rhizosphere of several tropical tree species .…”

“…1, and S. sinousa were discovered in savannah and postmining soil. A. scrobiculata was discovered in post-gold mining owned by PT Panca Logam Makmur and a mining community in Bombana (Tuheteru et al, 2020). AMF discovered in three locations was Glomus sp.…”

“…This study observed physical and chemical properties in the soil, spore density, species richness (Tuheteru et al, 2020), and AMF colonization (Brundrett et al, 1996). The soil was restored following the guidelines developed by Stanturf et al (2021) and Young et al (2022).…”

“…AMF served as a tool for restoring the degraded land and the disturbed ecosystem (Asmelash et al, 2016), and for the post-mining land (de Moura et al, 2022) in particular. Several studies showed that AMF was capable of accelerating the succession of natural vegetation in several post-mining land conditions worldwide, including coal (Husin et al, 2017), gold (Tuheteru et al, 2020), and asphalt (Tuheteru et al, 2022). According to previous reports, AMF could improve the growth of tropical tree species in soil media from a post-gold mining land at a nursery and field scale in Bombana (Arif et al, 2021;Husna et al, 2021a).…”
